1 . A system for dross removal on steel products, comprising: 
 a housing;    a heat source attached to the housing; and    an oxygen jet pointed perpendicular to the heat source.    
   
   
       2 . The system of  claim 1 , wherein the heat source is a flame.  
   
   
       3 . The system of  claim 1 , wherein the oxygen jet is coupled to a source of pure oxygen.  
   
   
       4 . The system of  claim 1 , wherein the oxygen jet is coupled to a source of compressed air.  
   
   
       5 . The system of  claim 2 , wherein the flame is perpendicular to a line of dross.  
   
   
       6 . The system of  claim 5 , further including a cooling system attached to the heat source.  
   
   
       7 . The system of  claim 1 , further including a plurality of wheels attached to the housing.  
   
   
       8 . A method of dross removal comprising the steps of: 
 (a) heating a portion of a line of dross with a heat source that is projecting perpendicular to the line of dross;    (b) moving the heat source along the line of dross; and    (c) moving a stream of oxygen behind the heat source.    
   
   
       9 . The method of  claim 8 , wherein step (a) further includes the step of creating a flame.  
   
   
       10 . The method of  claim 8 , wherein step (a) further includes the step of heating the portion of the line of dross to a temperature sufficient to make the dross molten.  
   
   
       11 . The method of  claim 8 , wherein step (b) further includes the step of determining a rate of movement at which the portion of the line of dross becomes molten.  
   
   
       12 . The method of  claim 11 , further including the step of cooling the heat source.  
   
   
       13 . The method of  claim 8 , wherein step (c) further includes the step of providing a source of pure oxygen.  
   
   
       14 . The method of  claim 8 , wherein step (c) further includes the step of providing a source of compressed air.  
   
   
       15 . A system for dross removal on steel products, comprising: 
 a housing;    a burner attached to the housing;    a cooling system pumping liquid around the burner; and    an oxygen stream pointed towards the heat source.    
   
   
       16 . The system of  claim 15 , wherein the housing has a plurality of wheels.  
   
   
       17 . The system of  claim 15 , wherein the oxygen stream is coupled to a compressed air source.  
   
   
       18 . The system of  claim 15 , wherein the oxygen stream is coupled to a pure oxygen source.  
   
   
       19 . The system of  claim 15 , wherein the burner is made of copper.  
   
   
       20 . The system of  claim 15 , wherein the burner is a pair of flames.
